Description

Close coupled type water jacket explosion-proof combustion engine gas exhaust manifold purifier

Technical field

The utility model relates to exhaust gas purifier for internal combustion engine technical field, particularly a kind of close coupled type water jacket explosion-proof combustion engine gas exhaust manifold purifier.

Background technique

Explosion-proof combustion engine is generally used for inferior flammable explosive gas one or the three explosion-proof places of class that exist of coal mine, for the machineries such as transportation, loading provide power, or provides generation driving force, there is certain shortcoming in existing anti-explosion diesel engine, purified treatment is not done in toxic emission, not up to standard, befouling environment.In tunneling sluggish in air circulation, serious harm workman's health.How to solve and administer anti-explosion diesel engine tail gas discharge, harm reduction, minimizing are polluted, and the mounting point of purification plant is most important.Because the Explosion-proof Design of exhaust system of explosion-proof diesel engine, waste gas is exported to waste water tank from body, be all double layer construction (inner tube high-temp waste gas passage, outside sandwich cooling water path) waste gas after supercooling, the inadaptable purifier of installing of temperature.According to actual conditions, select, adapting to purifier operating temperature, connect in the gas exhaust manifold of body, design and installation purification plant, this position waste gas just discharged do not have cooling, and high temperature can catalysis, oxidation, purification toxic and harmful and carbon soot particles.

Model utility content

Technical problem to be solved in the utility model is to provide a kind of features simple structure, practicality, and does not affect the water jacket type explosion-proof combustion engine gas exhaust manifold purifier of vent systems explosion-proof performance.

For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of close coupled type water jacket explosion-proof combustion engine gas exhaust manifold purifier, comprise explosive-proof sealed base plate, water sleeve exhaust steam passage, described water jacket is the rectangular cavities structure being fixed on explosive-proof sealed base plate, between water jacket internal layer and explosive-proof sealed base plate, it is exhaust steam passage, described explosive-proof sealed base plate is provided with at least two suction ports that connect with exhaust steam passage, described water jacket top is also provided with the exhaust pipe connecting with exhaust steam passage, exhaust pipe is cavity body structure, and cavity is communicated with water jacket, on described suction port, sealing is provided with Purified core, described exhaust pipe outer wall is provided with the cooling water inlet pipe being communicated with water jacket, on the outer wall of described water jacket end, be also provided with the cooling water outlet pipe connecting with water jacket.

The quantity of described suction port is identical with cylinder of internal-combustion engine quantity, distance between described adjacent suction port equals the distance between internal-combustion engine adjacent cylinder relief opening, described Purified core outer wall and suction port inwall are adjacent to and fix by auxiliary device, described Purified core is column cellular structure, hole count 200-300 order.

According to the close coupled type water jacket explosion-proof combustion engine gas exhaust manifold purifier described in claim 2, it is characterized in that: described Purified core is for being used the plumbous fibrofelt of siderochrome aluminium sheet and iron-chromium-aluminum felt or siderochrome aluminium sheet and siderochrome to roll the stratiform structure forming, described siderochrome surface of aluminum plate is provided with lineal shape or Z-shaped vertical passage, on described Purified core, is coated with catalyzer.

The effect that adopts technique scheme to produce: by close coupled type water jacket explosion-proof combustion engine gas exhaust manifold purifier is arranged on motor, the waste gas of discharge do not have cooling before, first by Purified core, reduce CO in waste gas, HC, NO _x, PM content, avoid befouling environment, at gas exhaust manifold outside sandwich, be provided with water jacket, by intake-outlet, be connected with high-order moisturizing, the circulating water being heated by waste gas rises, and forms circulation cooling, assurance gas exhaust manifold purifier surface temperature, lower than national requirement of explosion proof limit value, guarantees to use safety.
